CVE-2026-48814 · Severity: critical · CVSS 9.1 · Published 2026-06-17

Network-AI is a tool used to coordinate multiple AI agents. A security flaw in its server component allows anyone with network access to the server to take full control of the AI orchestrator without a password. An attacker could use this to change configurations, spawn unauthorized AI agents, or modify shared data, potentially leading to unauthorized operations or data tampering.

Technologies: [Jovancoding Network-AI](https://junglewise.ai/threats/technologies/network-ai), [network-ai (npm)](https://junglewise.ai/threats/technologies/npm-network-ai). Vendors: [Jovancoding](https://junglewise.ai/threats/vendors/jovancoding), [npm](https://junglewise.ai/threats/vendors/npm).

## How to fix

- network-ai (npm): upgrade to 5.7.2 or later

  ```sh
  npm install network-ai@5.7.2
  ```


## Technical details

The Network-AI MCP SSE server suffers from missing authentication (CWE-306) because the `_isAuthorized()` method in `lib/mcp-transport-sse.ts` returns `true` by default if no secret is configured. While a previous fix (CVE-2026-46701) restricted CORS to localhost, the server still defaults to an empty secret and permits unauthenticated requests from non-browser clients (such as curl or SSRF) or when bound to non-loopback interfaces (0.0.0.0). An attacker can invoke all 22 available MCP tools, including `config_set`, `agent_spawn`, and `blackboard_write`. The vulnerability is fully resolved in version 5.7.2, which implements a fail-closed authorization check and mandates a non-empty secret for the SSE server to start.
